The exhaled breath is a rich source of information about the inner life of the human body - but untangling this complicated molecular mixture into a quantitative measurement of its constituent components is currently an unsolved problem. This project aims to develop a new instrument that leverages the Nobel Prize winning technology of the optical frequency comb to enable analysis of such mixtures. It is expected that by combining a frequency comb source, with an innovative detector and a highly sensitive sampling system, a real-time spectral signature of each sample will be generated. Computational techniques developed by the radio astronomy community will then be used to extract concentrations of individual molecular components at the parts-per-billion level.Read moreRead less

Summary
Unravelling the intrinsic structure and stability of multiply charged anions in the gas-phase using photoelectron spectroscopy and mass spectrometry. Molecules possessing multiple negative charges are common constituents in chemistry, influencing a range of processes ranging from photochemical smog formation to protein structure in vivo. This project will develop new technologies to probe their molecular structure in the gas-phase, leading to a more rigorous understanding of these species.
The photons take charge: Elucidating the structure and stability of distonic radical anions by mass spectrometry and photoelectron spectroscopy. Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties.

Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties. This project will probe the fundamental structure and energetics of radical anions by modifying instrumentation to enable multi-step gas-phase ion synthesis to be efficiently coupled with anion photoelectron spectroscopy. These investigations are essential to revealing the scope of this phenomenon in free radical chemistry and biology and could inform future development of new catalysts for polymerisation.Read moreRead less

Summary
Probing the excited states of organic semiconductor systems with photoinduced absorption spectroscopy. Plastic semiconductors have the potential to revolutionise consumer electronics by enabling cheap, flexible and low power devices. The success of these devices depends on our understanding of the optical and electronic properties of the materials, which this project aims to address through the use of photoinduced absorption spectroscopy.
New laser and mass spectrometry-based tools for comprehensive structural elucidation of lipids and their biomolecular interactions. Lipid-related disorders such as obesity, diabetes and heart disease are reaching epidemic proportions. We propose the development of specialised instrumentation to identify and quantify lipids (fats) in tissue and culture samples thus providing Australian scientists with unique capabilities to investigate the mechanisms of disease.

Terahertz (THz) radiation is a disruptive technology promising revolutionary applications in fields as far ranging as biomedicine to counter-terrorism. But most of these applications have yet to see practical implementation, due to a lack of practical and robust THz radiation sources. This project aims to leverage on the project team’s expertise in non-linear optics to develop new methods of generating THz radiation in both continuous-wave and picosecond-pulse, quasi-continuous-wave regimes, which will complement and enhance current technologies. The outcomes intend to be THz sources generating frequency range, output power and temporal characteristics required for existing and emergent applications for THz radiation in scientific, commercial and defence sectors.Read moreRead less
